the colour of the scattered light depends on the size of the scattering particles. If the size of the particles is very fine, they scatter mainly light of shorter wavelength or blue light. If the size of particles is larger, they scatter light of longer wavelength . If the size of particles is large enough, they scatter light of all the colours and appear white

Bigger particles scatter longer wavelength  like red etc
smaller wavelength scatter small wavelength like blue etc
